curlMaster

cURL wrapper with response caching and cookie storage, methods GET, POST, HEAD.

Usage example, method GET:

use peterkahl\curlMaster\curlMaster;

$curlm = new curlMaster;

# Set the cache directory
$curlm->CacheDir = '/var/www/cache';

# If you want to use SSL/TLS, you need to set the location of CA certificate file.
$curlm->ca_file = '/srv/certs/ca-bundle.crt';

# If you need to set User Agent...
$curlm->useragent = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:55.0) Gecko/20100101 Firefox/55.0';

/**
 * Caching control & Maximum age of forced cache (in seconds).
 *
 * All responses are cached, but when this value is > 0, caching
 * will be forced regardless of the response headers.
 * Forced caching is useful when you expect the same response for each
 * request or when:
 *   -- debugging
 *   -- you cURL an API with request limit
 *
 * @var integer .... value 0 disables forced caching while header-dependent caching is still on
 *                   value >0 enables forced caching and overrides header-dependent caching
 *                   value <0 disables caching altogether (example -1)
 *

Usage example, method POST:

use peterkahl\curlMaster\curlMaster;

$curlm = new curlMaster;

# Set the cache directory
$curlm->CacheDir = '/var/www/cache';

# If you want to use SSL/TLS, you need to set the location of CA certificate file.
$curlm->ca_file = '/srv/certs/ca-bundle.crt';

# If you need to set User Agent...
$curlm->useragent = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:55.0) Gecko/20100101 Firefox/55.0';

$curlm->ForcedCacheMaxAge = 3600;

$data = array(
  'user' => 'admin',
  'pwd'  => 'oracle',
);

# The URL you want to cURL
$response = $curlm->Request('https://whatever.anything/login', 'POST', $data);

Cache Purging:

Although the cache is being purged automatically, you may want to purge the cache yourself (e.g. as crontab job).

use peterkahl\curlMaster\curlMaster;

$curlm = new curlMaster;

# Set the cache directory
$curlm->CacheDir = '/var/www/cache';

$curlm->PurgeCache();
